The Constant Current System is a DC power source with a built-in current probe designed for use in electrochemistry experiments, and as such eliminates the need for a separate power supply when performing electroplating and electrolysis experiments in Chemistry. It is capable of delivering 0.6 A at 5VDC Use the Constant Current System to explore Faraday's law and determine Avogadro's Number. Note: It can only be used in conjunction with its own built-in power supply. It cannot be used to measure the current of a circuit using a different power supply.

This is basically three Low-g Accelerometers mounted at right angles and all placed in a small box. Can be used  for studying the complex motion of an amusement park ride, a bungee jumper, or simply a toss in the air. Range: -50 to +50 m/s2 Typical accuracy: ±0.1 m/s2

Use the High Current Sensor in experiments that involve currents larger than 1 A, such as solar panels, hand generators, and other alternative energy projects. The High Current Sensor has a range of ±10 A. Current is measured with a Hall Effect sensor, which uses the magnetic field created by the current and therefore does not add a resistive element to the circuit. A metal shield over the Hall Effect chip reduces the influence of external magnets. A replaceable fuse protects the equipment and circuit

The Conductivity Probe determines the ionic content of an aqueous solution by measuring its conductivity. This has many applications in chemistry, biology, and environmental science. The Conductivity Probe has three ranges, providing optimal precision in any given range. Biology teachers can use this probe to demonstrate diffusion of ions through membranes. Chemistry students are able to quickly investigate the difference between ionic and molecular compounds, strong and weak acids, or ionic compounds that yield different ratios of ions. Environmental science students use it to measure TDS, total dissolved solids.  

Our Hand-Grip Heart Rate Monitor is ideal for determining a person's heart rate while mobile or stationary. With this sensor, heart rate can be monitored during, or after, exercise. The sensor consists of wireless hand grips and a receiver module that plugs into any of our data-collection devices. The hand grips sense the electrical signals generated by the heart. For each pulse detected, a signal is transmitted to the receiver module, and the individual's pulse rate is calculated. Do you need an interface? Why not go for our Heart Rate Human Physiology Kit?

The Instrumentation Amplifier monitors voltages from 20 mV to 1 V (DC or AC). It has several switch settings to allow you to select the best gain and includes auto-ID functionality for each of the six ranges. Input bandwidth of 10 kHz allows the capture of higher frequency signals. It is typically used to amplify the chart recorder or analog output of any instrument, such as a third-party gas chromatograph.

The Goniometer measures the angle of a joint, such as the knee or elbow. Use it to analyze the range of motion of a limb during different types of physical activity.

The EKG Sensor measures electrical signals produced during muscle contractions, and can be used to make standard 3-lead EKG tracings or surface EMG recordings. The EKG Sensor measures electrical signals produced by the heart. It uses three disposable electrodes. An EKG graph is displayed, demonstrating to students the contraction and repolarization of the heart's chambers. A package of 100 disposable electrodes is included with the sensor.
